What is arccos(0.14)?

Answer

arccos(0.14) ≈
81.9522° ≈ 1.4303 rad

Range: arccos x is an angle from 0° to 180°, so the answer is unique.

≈ — the value is not a table one; rounded to 4 decimal places.

arccos(0.14) is the angle α in [0°, 180°] with cos α = 0.14.

cos 81.9522° ≈ 0.1400

xyOP

α = arccos(0.14) ≈ 81.9522°

P ≈ (0.14, 0.9902)

P lies on the line x = 0.14 in the upper half of the circle, where sin α ≥ 0; highlighted: cos α = 0.14.
